The IIO current sunk must always respect the absolute maximum rating specified in Section Table 66. and the sum of IIO

(I/O ports and control pins) must not exceed IVSS.

The IIO current sourced must always respect the absolute maximum rating specified in Section Table 66. and the sum of IIO

(I/O ports and control pins) must not exceed IVDD.

Not tested in production, based on characterization results.
